Standards such as the IEC 801-4, DIN/VDE 0843-4
CENELEC HD 481

ge tests to be carried out on instruments and systems

using pulse bursts similar to those that occur in
practice when electrical equipment is switched on or

off, or when it is plugged in or disconnected
Electronic circuits of all types, especially modern
digital equipment, are very sensitive to these types

of interference pulses
The NSG 1025 Generator

ce sources
dards are met and, particularly where precision and

reproducibility are concerned, are often exceeded
new type of solid-state high voltage switch ensures
excellent pulse parameter stability and maintenance­free continuous operation
The instrument is equally suitable for laboratory and
field tests as well as for routine testing for quality
assurance purposes
by a selection switch with fixed settings for the pulse
parameters in conformity with the test classes contai-

ned in IEC 801-4

. An additional switch position

permits the continuous setting of the test voltage and
the free choice of the burst frequency for develop-

ment work and analytical measurements

In addition the NSG 1025 can generate fast single
pulses (5/50 ns transients) which are called for in
various test Standards and which are also useful for
detailed investigations in development laboratories

Internal and external trigger functions permit the

instrument to be flexibly adapted to the various needs
A single-phase mains coupling network is incorpora­ted in the unit which provides the coupling modes

called for in IEC 801-4 at the touch of a button besides

further coupling modes for special applications

The NSG 1025 is conveniently equipped with a

mains socket as well as universal safety sockets for
connecting the test object
The supply to the test object is separately switchable

Coupling clamps or coupling units for tests on data

lines or an auxiliary unit for three-phase coupling can

be connected via the HV coaxial connector
